The pandemic had a huge effect on education all over the world. Online education is not really effective at bringing students closer to nature, so spending quality time in nature has become very important as many believe it is essential for the students' normal physical and psychological development. Parents and teachers play a vital role in this process by holding outdoor classes. In our work, 372 working teachers from three countries (Serbia, Croatia, and Hungary) were asked to present their opinions about outdoor education. The results were analysed and compared between countries and with data collected four years ago. They considered it essential to hold as many outdoor classes as possible. However, they could only sometimes implement such intentions because of issues beyond their control.
